TIMOTHY BOSE, OF OORTLANDVILIJE, NEW YORK.

CANAL-BOAT PROPELLER.

SPECIFICATION forming part of Letters Patent No. 226,931, dated April27, 1880.

Application filed March 4, 1880.

To all whom it may concern:

Be it known that I, TIMOTHY ROSE, of the town of Gortlandville, in thecounty of Cortland and State of New York,'have invented certain new anduseful Improvements in Canal- Boat Propellers; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to an improvement to be used in the propulsion ofcanal-boats by steam-power.

In the drawings, Figure 1 represents a perspective view of the tube andwater-chamber, and Fig. 2, perspective and cross-section views of themachinery inside of the tube.

The letter A-indicates the tube, which extends lengthwise through thebody of the boat, and open at each end, and B the water-chamber, whichrises above the surface of the water.

The tube A being open at both ends, the water flows freely through, andthus permits the boat to be propelled by suitable machinery inside ofthe tube A. The letter O indicates the piston-rod, which playshorizontally, carrying the perpendicular shaft S back and forth in thetube A. Connected to the shaft S are wings F F, so hungnpon the shaft asto easily open and shut.

The piston-arms 0 c are secured to the shaft S both above and below thewings F F. These wings are so arranged and connected to the shaft thatwhen forced forward the resistance of the water opens them and, nearly.

(No model.)

permit them to pass through the waterin the tube without producing acounter action.

A hood, H, secured to the shaft S, guards the rear of the wings,'and bymeans of lateral extensions or braces to a, formingapart thereof, comingin contact with flanges b b upon the sides of the wings F F, the wingsare prevented trom opening beyond the desired angle or position. Betweenthe wings is a stop, vD, to prevent them closing completely togetherwhen withdrawn by the return stroke of the piston.

By turning the shaft S one-half around, which may be done by anysuitable machinery, the action of the water-wings is reversed and theboat propelled in an opposite direction.

In the bottom of the tube A is a groove or channel, 0, through which thebase of the shaft S is carried. In place of the groove 6, a single railmay be used, fitting into a slot in the base of the shaft S, to directits course.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination, with the tube and waterchamber, of the vertical shaftworking in ways or guides and carrying the vibrating wings provided withflanges b b, the hood H, formed with lateral extensions or braces to a,for the purpose, in connection with flanges b b, of preventing the saidwings from opening beyond the desired angle, and the stop D, forpreventing the wings from closing entirely when withdrawn by the returnstroke of the piston-rod, all arranged and combined to operatesubstantially as and for the purposesset forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

- TIMOTHY ROSE.
